Definitions related to scanning electron microscopy:
-
An electron microscopy imaging technique that is utilized to examine structural components of a sample by passing electrons through a specimen that has been coated with a heavy metal.CDISC TerminologyClinical Data Interchange Standards Consortium (CDISC), 2021

-
Technique of electron microscopy in which the specimen is coated with heavy metal and then scanned by an electron beam. The resolution is not as great as with transmission electron microscopy, but preparation is easier (often by fixation followed by critical point drying), the depth of focus is relatively enormous, the surface of a specimen can be seen (though not the interior unless the specimen is cracked open) and the image is aesthetically pleasing.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(microscopy, electron, scanning) Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
